Patients' preferences and their relationship with satisfaction following carpal tunnel release.

Patients' preferences for specific health outcomes in carpal tunnel syndrome (CTS) and their association with demographic factors and satisfaction with the results of surgery after 6 months were evaluated. Two hundred fifty subjects with CTS and enrolled in a prospective community-based cohort study in Maine completed a preference questionnaire before surgery. Patients were asked to specify the single most important reason they decided to undergo surgery and to rate the importance of improvement in 10 areas, including lessening of specific symptoms and improvement in specific functional states related to CTS. The single most important reason for CTS patients to have surgery was relief of night pain (37%), followed by relief of numbness (21%) and relief of daytime pain (13%). When patients were asked to rate the importance of obtaining relief from specific symptoms and improvement in specific functional states, relief of numbness received the highest rating, with 94% of the patients answering that it was extremely or very important. Workers' compensation recipients, patients with less than a college level of education, and patients with more severe symptoms and functional impairment at baseline assigned higher importance to symptom relief and functional improvement. Controlling for other predictors, higher preference for improved strength was associated with lower satisfaction with the results of the surgery at 6 months. Most CTS patients undergoing surgery have realistic preferences for health outcomes that are influenced by demographic and clinical characteristics; however, physicians should pay attention to unrealistic preferences that might influence patients' satisfaction with surgical results.
